2 v corms-i tail way C (Fig. 5) in which fits a guide bar M along whichthe cylinder may be longitudinally adjusted and to which it may be fixedby a setscpew M. Ihe guide bar is connectedto a sleeve N, sliding on thebar G, by a swivel joint'oi common construction, shown in Figs. 5 and-6,whereby the cylinder may be inclined in its plane of movement along therod G and thus the ballast beneath the rails be readily tamped from theinside or outside of the rail, Then the piston is raised to the upperend of its path, the tamping tool is above the plane of the ties, and bythen rocking the cylinder upon the rod G it will be thrown above theplane of the rails and may be carried from one side of the rail When thetool is thus raised and the middle of the toggle-bar is also raised, thewhole apparatus may be pushed along the rails to tamping positionalongside a difi'erent tie.

In use, two tampers are ordinarily arranged as indicated in Fig. 1, oneattendant for each holding down the corresponding toggle-bar andcontrolling the tamping while a third man moves both cylinders along therods G. One man readily puts'a tamper in place and removes it from thetrack, and the three easily lift on and oh the track the light motorcar, not shown. I

Fig. 7 hows a form -in which vertical brackets O, 0' support the .rodGwhich in this case has free ends extending out from the railsapproximately to the ends of the ties. In this form the devices tampbetween and beneath the rails as before, but they must be transferred tothe outer ends or" the rod G for tamping outside the rails. In thisfigure, the plate 0, corresponding to the plate H of the primary form,is shown as plane, and especially adapted for use over a heavy fishplate P and its nuts or bolt ,heads Q. Such a plate may be quicklysubstituted for the plate H of the other form, when desired, if thepintle be withdrawn as beforesuggested.

Cit

In order that the vibration of the rod G may be lessened when tampingnear the middle of the tie, I in some instances support it at pointsover the rails, respectively, by extensible and readily removable strutsS, Fig. 2, of any convenient construction.

Many changes may be made without passing the proper limits of myinvention and I do not, therefore, wish to limit my claims tothe'spccific embodiment shown.

What I claim is:

1. In tamping apparatus, the combination with a fluid pressure cylinder,a piston working'in the cylinder and provided with a noncylindricalpiston rod, a tamping tool car .ried by the piston rod, and means forsupporting the cylinder above the plane of the tie to e operated upon.2. In a tie tamping apparatus, the combination with a transverse bar, ofsupports for said bar adapted to rest directly upon the rails, means forclamping the supports to the rails, and a fluid pressure tainping deviceslidably mounted upon said bar.

3. Intie tainping apparatus, the combine;- tion with a transverse bar ofa length materially greater than the width of the track, brackets daptedto be clamped to the rails to support, respectively, the outer ends ofthe bar, and fluid pressure tamping devices slidably mo'unted upon saidbar.

s. In a tainping apparatus, the COlllbllltl,

tion with a transverse bar, of means for se- U curin the bar to therails, a fluid pressure cylin er mounted to slide freely along said barand to swing freely in planes parallel thereto, a'piston working in saidcylinder, and a tamping tool carried. by said iston; whereby ballast maybe tainped ob iquely beneath the rail.

5. In a tamping ap aratus, the combination with atransverse ar, of meansfor rigidly supporting the same above the rails, means for ri 'idlyclamping the supports to the rails, a cydinder-supporting block mountedto slide along the bar and to swing trans- -versely thereon, and atool-carrying fluid pressure cylinder mounted upon the block to swing inplanes parallel to the bar. 6. In a tamping apparatus, the combinationwith a transverse bar above the rails when in operative position, meansfor rigidly supporting the bar from the rails, a cylindersupportingblock mounted to slide along the bar and to rotate about the same,fluidpressure cylinder mounted upon the bloclr to swing in planesparallel to the bar, and means for adjusting the cylinder, in adirection parallel to its axis, upon the block.

7. In tie 'tamping apparatus, the combination with a transverse bar, ofmeans for rigidly supporting the same fromv the rails, of atool-carrying iluid-prcssurc cylinder mounted to slide freely upon thebar and to swing freely in planes transverse thereto and parallelthereto. v

8. In a tie taniping apparatus, the combination with a transverse bar,of means for rigidly supporting said bar from the rails, a toolcarrying, fluid pressure cylinder mounted -transverse to the bar toslide thereon and to slide in the direction oi its own axis and also toswing in planes transverse to the bar and parallel thereto,respectively, and means for at will locking the bar in any position towhich it may be adjusted by sliding in the direction of its axis.

whereby the apparatus when-leftby the operator is always free tolee-thrown aside by a train.

10. In tie tainping apparatus, the combination wilh a suitable support,of tamping deviees mounted upen said support, two clamps for rigidlysecuring the support to the rails, respectively, and'a toggle-bar freeto be flexed by lateral pressure, and adapted to be interposed betweenthe clamps and to force both into engagement.

11. In tie tanlping apparatus, the combination with a suitable support,of tamping devices mounted .upon said suppert, two clamps for securingthe support to the rails, a toggle-bar adapted to be interposed betweenthe: clamps and to force both to en-' gage the rails,

means for holding the ends of the toggle-bar at. the same distanee fromthe tops of the rails, and a leveling device attarhed to the toggle-bar:

12. In a tie taniping apparatus, the com-' clamps for securing thesupport to the rails, respectively. a toggle-bar adapted to beinterposed between the two l-lamps and to force them into engagement,and a spring arranged to resist straightening ot the toggle bar.

In testimon whereof I afiix my signature in presence ov two witnesses.
